Grout Sealer Applicator

ABSTRACT

The Grout Sealer Applicator is a plastic wand type tool used to apply grout sealer. The applicator wand can be attached to the end of a chemical sprayer trigger. The applicator has a long tubular body with an angled brush at one end and a connection nut on the other. The applicator shaft is hallow, allowing grout sealer to flow from the nut end, through the shaft and into the brush. The grout sealer applicator gives the user the ability to apply sealer directly onto the grout surface in a standing position. 
     The Grout Sealer Applicator is a wand type tool used to apply grout sealer. The applicator wand can be attached to the end of a compression sprayer trigger. The applicator has a long tubular body with an angled brush at one end and a connection nut on the other. The applicator shaft is hallow, allowing grout sealer to flow from the nut end, through the shaft and into the brush. The grout sealer applicator gives the user the ability to apply sealer directly onto the grout surface in a standing position.

BACKGROUND OF THE INVENTION

This invention relates to grout sealer applicators. More over it relatesto devices used to apply grout sealer, such as mechanical.

Typically grout sealer is applied with a paint roller or brush. Usuallypoured directly onto the grout and tile, then painted or rolled into thegrout lines.

Grout sealer that is applied by brush is not only time consuming butnormally done on the knees of the user, in an uncomfortable position.

If it is being rolled into the grout lines it is messy and wasteful.

Therefore it would be very advantageous to remedy this process and otherproblems related to the above.

The object of this invention is to give the user a comfortable way toapply grout sealer accurately and without waste, saving the user bothtime and money.

Another object of this invention is to give the user more control overthe amount of grout sealer being applied, minimizing mess and clean uptime.

SUMMARY OF THE INVENTION

To achieve the objects described in the above background the groutsealer applicator wand should be designed as follows:

A wand designed to attach directly to the threaded end of most or allchemical sprayer triggers. If needed a special threaded adapter can beused with the applicator to fit other triggers.

The wand has a hole through the shaft that allows grout sealer to flowfrom the connection nut into the brush end. From the brush it is applieddirectly and accurately onto the grout surface, keeping the sealer inbetween the lines and not on the tile.

The length of the applicator wand should be about 3 feet or long enoughthat it can be used in a comfortable standing position.

The adjustable switch goes from high to low setting. Depending on theusers speed and accuracy they can choose the setting that best suitsthem. The switch is mounted into the brush end housing, inline with theshaft hole.

The brush is angled to compensate the users own angle at which theystand giving the brushes more surface contact. The brush bristles shouldbe of high to medium quality to ensure the applicator can be usedrepeatedly and to ensure that no bristles come loose during applicationof the sealer.

To prevent excessive pressure at the nut & trigger connection andpossibly stripping the threads; the body of the grout sealer applicatorwand should be strong, flexible but also light weight.

The connection nut should have enough threads to compensate for thelength and weight of the wand, ensuring a good and strong connection tothe sprayer trigger.

If needed the connection nut can also contain an internal o-ring to seatand seal the connection.

The grout sealer applicator wand could be designed with its own chemicalsprayer and trigger or as stated can be used with most standard chemicalsprayers and triggers.

The applicator pays for itself on jobs that are 800 square feet or moreof tile and can be stored and used every year that sealer needs to beapplied.

Leftover grout sealer can be saved in the sprayer reservoir and usedagain. Only the brush needs to be washed after use.

A wand designed to attach directly to the threaded trigger end of most,all or one compression sprayer. If needed a special threaded adapter canbe used with the applicator to fit most, all or one compression sprayertriggers.

The grout sealer applicator wand could be designed with its owncompression sprayer and trigger or as stated can be used with moststandard compression sprayers and triggers.

BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 1 is a side view of the Grout Sealer Wand, showing the entire bodyof the applicator, the angle of the brush, the adjustment switch and theconnection nut end.

FIG. 2 is an angled view of the applicator brush end, without the brushbristles or the selector switch.

FIG. 3 is an angled view of the applicator shaft, without the connectionnut or brush. This figure shows a detailed look at the nut end of theshaft, without the connection nut.

FIG. 4 is a side view of the applicator connection nut and threads.

FIG. 5 is a side view and an internal view of the high and low selectorswitch.

FIG. 6 is a view of the grout sealer applicator wand in action orworking.

DETAILED DESCRIPTION OF THE INVENTION

Now to the drawings in which similar reference characters indicate thecorresponding parts throughout different views. First we look at FIG. 1position 1 which shows direction of sealer flow through the middle ofthe applicator shaft, from nut end to brush end. Next FIG. 1 position 2points to the threads in the connection nut. Then FIG. 1 position 3points to the body or shaft of the applicator wand. Next FIG. 1 position4 shows the length of the shaft to be about 3 feet. FIG. 1 position 5points to the high and low setting switch. FIG. 1 position 6 points tothe hole at the brush end where grout sealer flows out and into thebrush bristles. FIG. 1 position 7 points to the angled brush bristles.

Now looking to FIG. 2 position 1, which shows an o-ring groove on thewall of the high and low selector slot. Next FIG. 2 position 2 shows thehole at the brush end, where the sealer will flow out. FIG. 2 position 3shows another hole, where the sealer flows into the selector switch,then to the brush side and out the brush end. FIG. 2 position 4 showsone the four small round indentations used for locking the high and lowselector switch into position. The indentations should be evenly spacedto provide a secure lock.

Next we look at FIG. 3 position 1 which shows the direction of sealerflow through the hollow shaft of the applicator. Then FIG. 3 position 2points to the shaft of the grout sealer applicator wand. FIG. 3 position3 points to the hole at the nut end of the applicator shaft. FIG. 3position 4 shows an optional o-ring that could be used at the nut end toprovide a better seal.

Now to FIG. 4 position 1 which shows the threads inside the applicatorconnection nut. There should be enough threads to insure a solidconnection. FIG. 4 position 2 points to the overall length of theapplicator connection nut. Which should be about ½″ or long enough tosupport the length and weight of the grout sealer applicator wandwithout stripping the threads of the connection nut or trigger.

Next FIG. 5 position 1 shows one of the four locking knobs that shouldhold the selector switch into place. FIG. 5 position 2 points at theselector switch o-ring. FIG. 5 position 3 shows the hole of the lowside. FIG. 5 position 4 points to the larger hole which is the highside. FIG. 5 position 5 shows an internal look at the low side hole ofthe selector knob. FIG. 5 position 6 shows an internal look at the highside hole of the selector knob.

In FIG. 6 position 1 shows the chemical sprayer pump and reservoir. FIG.6 position 2 shows an average person using the grout sealer applicatorwand in a comfortable standing position. FIG. 6 position 3 points to theapplicator wand making contact with the grout lines.
